植入式接触镜矫正高度近视眼的临床疗效观察

Clinical observation of implantable contact lens implantation for high myopia

目的评价高度近视眼患者行植入式接触镜(Implantable contact lens,ICL)术后的临床效果。方法选取在笔者医院行ICL植入手术的高度近视眼患者32例(64眼),随访观察术后1d、1W、1个月、3个月患者的裸眼视力(uncorrected visual acuity,UCVA),最佳矫正视力(best corrected visual acuity,BCVA),眼压(intraocular pressure,IOP)、角膜内皮细胞计数、前房深度(anterior chamber depth,ACD)、总高阶像差,并与术前进行对比分析。结果术后1d、1W、1个月、3个月的UCVA、BCVA与术前比较均有提高,且差异均有统计学意义(P<0.05)。术后1d、1W、1个月、3个月的ACD与术前比较均降低,且差异均有统计学意义(P<0.05)。术后1 d眼压与术前比较,差异有统计学意义(P<0.05),术后1 W、1个月、3个月眼压与术前比较无统计学意义(P>0.05),术后随访各时间点内皮细胞计数、总高阶像差与术前比较均无统计学意义(P>0.05)。结论植入式接触镜手术治疗高度近视眼安全、有效。

Objective To evaluate the visual effect in high myopia patients after ICL implantation.Methods Thirty-two high myopia patients（64 eyes） underwent ICL implantation in author＇s hospital were enrolled in this study. Their uncorrected visual acuity,best corrected visual acuity,intraocular pressure,corneal endothelial cell density,high order aberration after ICL surgery one day,one week,one month,three months were observed and compared. Results UCVA and BCVA increased significantly（P〈0.05） at one day,one week,one month,three months after surgery. ACD decreased significantly（P〈0.05） at one day,one week,one month,three months after surgery. IOP decreased significantly（P〈0.05） at 1 day after surgery,but there was no significant difference in high order aberrations and corneal endothelial cell density after surgery（P〉0.05）. Conclusion ICL implantation in high myopia is safe and effective.
